Unformatted text preview: b. (1.5 points) What is the flow velocity at the point the water flows into the ditch? Explain your reasoning in one brief sentence, then give any relevant equations and the numerical result. 2. (2.0 points) Consider the portion of a fluid circuit in equilibrium shown in the figure. Water flows with current I into the large diameter tube, then down a height change Δ h, to a smaller diameter tube. Assuming there is minimal resistance to the flow, indicate on the diagram the points of greatest and least pressure. Explain your reasoning below the diagram, using the Bernoulli equation. continuity: I = A 1 v 1 = A 2 v 2 Bernoulli equation: Δ P+ Δ ( ½ρ v 2 )+ Δ ( ρ gh) = Δ E pump /vol  IR...
